Russell Brand recently announced his divorce from California Gurl singer Katy Perry. Unusually among celebrities, the former couple did not have a prenuptial agreement, which means that Perry may be left paying millions of dollars to her ex-husband.

Katy Perry and Russell Brand’s 14-month marriage is over, but according to experts, they made a mistake even before they walked up the aisle. At least, Katy did.

Now she could lose millions in her pending divorce from the British comic actor.

Their whirlwind courtship and subsequent engagement and marriage has ended almost as quickly as it began, but the brief relationship could be a pain in the pop star Katy Perry’s pocketbook for years to come.

Back in October 2010, Brand was adamant that their wedding was purely about their love for each ther.

“So it ain’t selling the pictures, ain’t doing no prenup. (But) it’s like a normal thing,” he said.

Now, Brand (36) could be laughing all the way to the bank. He stands to make an estimated $30 million from the 27-year-old sex symbol’s fortune, because the couple never signed a prenuptial agreement.

Former heroin addict Brand has turned his life around and got clean and sober. It’s even alleged that a major reason for their divorce is that he is a home body and Perry is a party animal. But he is set for a major injection of cash into his bank account under California’s community property law. The state’s community property clause demands a 50/50 split of marital assets in cases of divorce where there is not a prenup already in place.

Perry is estimated to be worth over $44 million, according to Forbesmagazine, but that could be as much as $70 million following her successful 133-day California Dreams tour, her platinum-selling Teenage Dream LP and a new Katy Perry doll manufactured by Barbie-makers Mattel.
